Electric cars = SLOW

Torque is a measure of force. It is possible to apply force with no reaction/movement. 100% TQ at 0 RPM IS correct. Hydraulic motors can do the same thing.

If they weren't able to apply TQ at 0 RPM, they would never start moving.

maybe this one is better:

Beat me to it

Our servo motors for the refueling machines we build are a good example of 100% torque at 0 RPM. You can hang a fuel assembly off the hoist, with no brakes applied, and it will still not move. The motor has not been given a command to move, so it will apply as much torque as it neccessary so that the hoist does not move. You can hook up a hand wheel and try to crank the hoist up/down, but nope. It will apply full torque if it needs to, to hold that thing right where it is. Full torque at 0 RPM.

I guess that's true. I didn't think about it like that!
